Frequently Asked Questions
Q
What makes a single-seat ceramic ball valve different from a standard metal ball valve?
A single-seat ceramic ball valve uses advanced ceramic materials (such as ZrO₂ or Al₂O₃) for the ball and seat, offering significantly higher hardness, wear resistance, and corrosion resistance compared to standard metal valves. The no-cavity design also prevents clogging and scaling, making it far more reliable in abrasive or chemically aggressive slurry applications.
Q
What sealing class does the ceramic ball valve achieve?
The single-seat ceramic ball valve achieves a high sealing level of up to ANSI Class VI, ensuring tight shut-off and completely leak-free performance even under demanding process conditions.
Q
Which ceramic material is most suitable for highly corrosive acid environments?
For most strong acid environments such as H₂SO₄, HCL, and HNO₃, both ZrO₂ (Y-TZP) and Al₂O₃ (99%) demonstrate excellent corrosion resistance (rated "A"), making them the top choices. SiC is also highly resistant across nearly all listed media. The selection should be based on specific concentration, temperature, and media type as shown in the Anti-Corrosive Performance Reference Table.
Q
What are the available ball core types and how do they affect flow control?
The ceramic ball valve is available with O-type, V60°, V45°, and V30° ball cores. The O-type core provides the highest flow coefficient (Cv) for full-bore isolation duty, while the V-notch cores (V60°, V45°, V30°) offer progressively finer flow regulation and better control characteristics for throttling applications. The V30° core provides the most precise flow control with the lowest Cv values.
Q
How does the scraper-type valve seat prevent scaling and crystallization?
The scraper-type valve seat is engineered to mechanically clean the sealing surfaces with every open/close operation. As the ball rotates, the seat edge scrapes away any deposited crystals, scale, or buildup from the sealing zone, maintaining a clean contact surface and ensuring consistent sealing performance over long-term service without manual cleaning.
Q
What industries and media types is this ceramic ball valve most recommended for?
This valve is most recommended for industries handling abrasive, corrosive, or scaling media, including titanium dioxide (TiO₂) production, salt chemical processing, petrochemical catalyst units, mining and mineral processing (ore slurries, concentrates, tailings), hydrometallurgy, flue gas desulfurization (FGD) systems, and steelmaking slag slurry applications. It excels wherever conventional metal valves fail due to wear or chemical attack.
